/ˈjʊrənəs/,

/jʊˈreɪnəs/

Origin: Formed within English, by derivation; probably modelled on a French lexical item. Etymons: uranium n., -ous suffix.

Etymology: < uran- (in uranium n.) + -ous suffix, probably after French uraneux (1826 or earlier). Compare earlier uranitic adj., uranic adj.¹, uranious adj.

1. Chemistry. Of or relating to uranium in one of its lower oxidation states (often +4); designating such a state. Contrasted with uranic adj.¹
